KB3 Otto Sirvis

So last Sunday I took my CHEVY to a recommended auto service department in Modesto, CA. There was a weathered sign noting “KB3 Otto Sirvis” on a lone country road. This guy had all the tools one would need to take ottos apart but looking around it seems nothing has been put back together. Still, I took a chance and this nice man directed me onto his mobile lift. Then he proceeded to remove parts from my Chevy. Next, he started drilling and cutting into the rear bottom plate which he removed. Luckily, I had brought a panel replacement just in case he went wild with drills and saws. Of course he needed more tools and went off on a buying spree for more tools. He says he likes working on Chevys and proved his expertise while replacing bolts and just put any bolt in where there was a hole. He did an excellent job and even swept up the shop waiting for his next victim, er customer. Of course he took my Chevy out for a test drive. It was a long drive..said he had lunch while he was out. I think ALL Chevys should try this place out.

Well it sort of was like that.

Ken was kind enough to offer his lift for a procedure I wanted to do on my C8. Since it has a DCT the filter for the DCT needs to be changed at prescribed intervals. To do this one must remove the undertray that has 30+ bolts with 3 different head sizes. To make this an easier job we cut the panel and installed a hinged door which gives quick access to the filter and drain and fill plugs. We also installed a safety latch in case the panel latch failed. During this process we also did an oil change. Ken’s shop has almost everything one would need although my plastic oil filter wrench cap was useless because the prior oil change done by a Chevy dealer seemed to have welded it on. And Ken said his metal saw blades were too dull and he needed new ones. So off he went to Lowes to buy more tools. I really didn’t take many pics because well we were working and it just didn’t occur to me to document everything. Panel out, door installed, oil change in about 3 hours. Thanks to Ken again for his shop, tools, expertise and help.

Gee, what a great design that you have to remove a panel with 30 bolts to change a filter. What was the General thinking?

That the old geezers who buy Vettes wouldn't have an issue with it since they bring the cars in for even basic maintenance anyway.
 
Terry is right. This DCT filter change can cost almost $1k at a dealer. Many a used C8 owner is finding that such 'required' maintenance hasn't been done and that their new to them C8 isn't covered under warranty because of that.
 
They really try and charge a grand for a filter replacement? Crazy. 30 bolts sounds like a lot but it's really just a belly pan and I imagine all easily accessible with the car off the ground. Quick work with an electric impact to get on/off. Especially when you have a lift set up for it like a dealer would. Would seem cost effective though in the original design to include a removable flap type plate though. Pretty common on new cars now with plastic bottom covers.
 
The bottom of the C8 is completely covered. Also this plate uses E16 bolts. Not very friendly. If I was to remove the plate more often I would change them out to normal 6 point bolts. But now with my door panel add on it will not require the plate removal.
